Summary: Copper adds LinkedIn integration

Why It Matters: This change shows Copper is making it easier to find and add new leads.

What Changed:

• The "Coming soon" label was removed from the LinkedIn integration feature. This means the LinkedIn integration is now live.
• The "Integrations" list was updated to include LinkedIn and JustCall.
• The "Contracts & proposals" section was updated to mention drafting in Google Docs.
• The description for "Pipelines" was updated to include "AI-powered flags and alerts."
